About these numbers Counts come live from PubMed and ClinicalTrials.gov. "Randomized trials" counts PubMed papers tagged as randomized trials that mention the peptide, which can include studies that only measure it rather than test it as a treatment. "People use it for" describes common claims, not recommendations. Educational only, not medical advice.
